BELT-DRIVEN TWISTING-MACHINE.

SPECIFICATION forming part of Letters Patent N0. 755,261, dated March 22, 1904. Application filed February 25, 1903. Serial No. 145,109. (No model.)

ment in Belt-Driven Twisting-Machines, of

which the following is a specification.

My invention relates to that class of twist:

ing-machines in which the spindles are arranged in groups and thethreads drawn from bobbins on certain spindles of a group are twisted and doubled and after being doubled are again twisted and laid upon a bobbin on another spindle of the group.

The object of my invention is to provide a.

way of driving the spindles of the successive groups by belts and of stopping each group of spindles when desirable independently of the other groups of spindles driven by the same belts.

My present invention is an improvement on a device shown in a former patent granted to me, numbered 67 6,057 and dated June 11, 1901, for belt-driven twisting-machines.

In the drawings, Figure 1 is, a front elevation, and Fig. 2 is a plan view, of an abbreviated machine containing my device. Fig. 3 is an end elevation of an individual group of spindles and their connecting parts.

Throughout the drawings similar letters indicate similar parts.

The frame of the machine is shown at a.-

cured to the frame and a further support (not shown) at its upper end. Upon the horizontal shaft (0 is the bevel-gear 0. Upon the vertical shaft d is thebevel-gearc. Upon.

the shaft (Z are secured two pulleys and f.

At the other end of themachine are carrierpulleys e and f to correspond'to. the pulleys e and f. A belt Z1 passes around the pulleye and runs to and drivesthe pulley a; Another belt, Z, passes around the pulley f and runs to and drives the pulley f. The revolving of A perpendicular the shaft I a by means of the pulley b will, through the medium of the bevel-gears c and 0, impart motion to the vertical shaft 0?, cause the pulleys e and f to revolve, and the belts hand Z to travel. The pulleys e and f have movable bearings in order that the respective belts may be tightened, as will be hereinafter explained.

Pulleys m 972, one on each side of the machine, cause the belt is to travel parallel with the machine and the going and returning parts of the belt to run parallel with each other without regard to the fact that the diameter of the pulley e is greater than the distance between the going and returning parts of the belt k. 7 As the parts are shown in my drawings the distance between the pulleys m m equals, except as to the thickness of the belt, the diameter of the carrier-pulley e. The belt Z runs parallel with the machine, and the going and returning parts of the beltrun parallel with each other, owing to the pulleys f and f being of the same diameter.

At 9 are shown twisting-spindles the pillars or supports of which are secured to the rail (0 At g are pressure-pulleys,mounted in brackets g which brackets are mounted on and turn on the pillars that support the spindles g. A spring 9 coiled about the sleeve of the bracket g has its lower end secured at the base of the pillar of the spindle 9, while its end 9 presses against the bracket g and tends to turn the ley 'gi tothe spindle to which it relates.

"Pulleys 2', mounted on the raila maintain the running-line of the belt Z. i

A plate oloosely encircles the pillar of each spindle g, the hole in the plate beingso large that the plate can be moved a limited distance without being confined by the pillar. An extension of the holein the plateo forms a slot 0 through which a stud 0* projects, the lower end of the stud being secured to the spindlerail. Upon the stud as shown on one plate 0 in Fig. 2, are a washer, a spring, and a nut 0 to hold the plate o down to the rail (0 at the same time allowing the plate to be loose enough to slide readily in and out upon the rail, guided by the stud 0 in the slot 0 Upon the front of the plate'o are secured the supports of two spindles h h. When the plate 0 is moved inward, these spindles bear against the belt Z and are driven by it. When the plate 0 is moved outward, the whirls of the spindles it h are clear of the belt Z.

Mounted on the'back of the plate 0 and behind the whirl of the spindle g is a spring 0 carrying at its upper end a brake-shoe 0'.

-' At 0 is an upward projection on the plate 0. At'g is a downward projection from the bracket 9 If the plate 0 is pushed forward, the part 0 will impinge against and thrust forward the part 9 and the pressure-pulley will be moved so that it will cease to press the belt 70 against the spindle At the same time the brake-shoe 0, moving forward with the plate 0, impinges against the whirl of the spindle g and overcomes the momentum of the spindle. A plate n is secured beneath the rail a For convenience I fasten it to the rail by the same nut that secures the pillar of the spindle g.

The plate has lips a that grip the rail a and hold the plate steady. At the forward end of the plate a is a jaw 72. A stud n is adjustably secured by a nut in this jaw 72*. A brake 91 having the brakefingers n rests on a shoulder 'on the upper part of the stud nf. The brake is free to turn upon the stud. The brake-fingers n are contiguous to the spindles h h. When the plate 0 is moved forward, the spindles h h, mounted thereon, are carried with it, and so out of contact with the belt Z, and the whirls of the spindles are forced into contact with the respective brake-fingers 02, of the brake 92 thus overcoming the momentum of the spindles h h.

If the brake-shoe 0 for the spindle g were rigid, a great nicety of fitting would be required to have the two brake-fingers n brake the spindles h it and the brakeshoe 0 brake the spindle g at the same time, in view of the fact that both brakes are brought into action by the movement of the plate 0. It is for this reason that the brake-shoe 0 is mounted \on the spring 0 The adjustment of the parts issuch that the brake-shoe 0 touches its spin dle g before the respective spindles it touch their brake-fingers 02 The spring 0 then bends as the plate 0 is pressed forward until the whirls of the spindles it touch their respective brake-fingers a The fact that the brake n is free to turn upon the stud n also makes less nicety of fitting necessary, as if one brake-finger 92 comes into contact with'its spindle before the other The outward movement of the plate 0, to which I have referred in the foregoing description, is brought about through the action of the rod p. The vertical lower end of this rod passes through a slot in the fixed plate a. A wedge 9 upon the rod passes through a slot in the sliding plate 0. 'Upon the rod 2 is a spring 10 one end of which is secured to a bracket q and the other end of which is secured to a collar on the rod The bracket q is the usual bracket employed to hold fallers for the threads or a faller-lever. This bracket is secured to a rail of the machine.

At 9 is shown a slotted roller for actuating fallers or a faller-lever. These parts have been shown without detail because they do not relate to the present invention.

'At 9 is a latch-spring secured to the rod 9.

At the upperend of the latch-spring is the latch 10 The bracket g has a slot through which the'rod 9 passes. The latch-spring 19* also passes through this slot. The latch 19 impinges against the bottom of the bracket 4 A starting-lever s is pivoted at s and has as a fulcrum the pin 19 in the rod 1). It will be noticed that the upper part of the rod 29 is prevented by an abutment in the bracket (1 from being moved inward, while the latchspring 10" prevents the rod from being moved outward. It will also be noticed that the vertical lower part of the rod p,'passing through a slot in the fixed plate n, is controlled by said slot, so that it cannot be moved inward or outward therein. The result is that the rod 19, though it may be moved up and down, maintains its upright position under all circumstances. The wedge 0, passing through the plate 0, acts to move the plate either outward or inward as the rod is moved up or down, the front part of the wedge acting to move the plate outward and the rear part of the wedge acting to move itinward. When the parts are running, the wedge is between the fixedplate n and the movable plate 0, the upper part of the wedge extending through the plate 0. When the rod 9 moves upward and the wedge 12 forces the plate o outward, the force of the moveinent of the plate is exerted against the rear of the slot in the platen. Whenthe rod is lowered and the wedge moves the plate inward, the force of the movement of the plate is exerted against the front of the slot in the plate n. The fact that the plate a is secured beneath the rail a while the plate 0 slides on the rail (0 furnishes the necessary space between the two plates for the wedge 0 to have suflicient of its incline below the plate 0 to be ready to perform its work when the rod 9 is moved upward. At a is an upward extension of the plate a, which supports the rear of the movable plate 0.

When through any cause the stop-motion of the machine is brought into action, the upper part ofthe latch-spring 2* will be pushed inward, the latch p will be moved away from ITO its bearing on the bracket q, the spring 19 will force the rod 19 upward, the fulcrum 9 will throw the forward end of the startinglever s upward, the wedge '10 on the rod pwill force theplate 0 outward, and the outward action of the plate 0 will move the two spindles h h from contact with the belt Z andagainst their respective brake-fingers a The outward movement of the plate 0 will also cause the part 0 to impinge against the part g" and move the pressure-pulleygf-so that it will cease to press the belt is against the spindle 9. At the same time the outward movement of the plate will bring the brake-shoe 0 into contact with the whirl ofthe spindle g All the three spindles'comprising a group will then have ceased to -revolve. When the lever 8- is thrown upward, it can beseen at a considerable distance and acts as a signal'to the operator that the parts are stopped.

h In Fig. 2 of the drawings the central group on each side of the machine is shown with the spindles and their driving means separated and the spindles stopped, while the groups to the right and left of the stopped groups are shown running. t

r The machine will of course be provided with feed-rollers and with connections between them and the-rodp to causethe upward movement of the rod '19 to move the feed-rollers from contact with their driving-roller and stop the feeding of the threads at the same time that the spindles cease to revolve; but as such parts form no part of my present invention I have not shown them in the drawings.

,VVhen the threads have been repaired and the group of spindles is to be started, the op- ..erator presses down the outer end of the lever 8, and said lever, hinged at s, presses upon the pin 10 and forces the rod 49 downward against the pull of the spring p until the latch-spring p throws the latch 10 under the bracket g. The downward movement of the rod p causes the wedge pto slide the plate 0 inward, thusbringing the twospindles/tinto contact with the belt Z and allowing the spring 9 to force the pressure-pulley g against the belt is and cause thebelt -7 to press against and drive the spindle g. The downward movement of the rod 19 of course allows the feed: ing mechanism for the threads to resume operation at the same time that the spindles are I again revolved.

It will be observed that the two belts hand z,

- both driven from pulleyson the upright shaft d, naturally both travel in'the same direction.

were driven by the oppositesides of a single belt, as is the case in the former patent granted to me for belt-driven twistingmachines, dated June 11, 1901, and above referred to. The action of the guard-pulleys j. and the pressure pulleys g is similar to the action of likedevices shown in said former patent. The advantages of the presentdevice over that shown in my former patent are that the spindles g and it it can be farther apart than when both have to gain their motion from one belt and thatthe relative speeds of the spindles g1 and it can be varied by changing the size of the pulley e. The greater distance between the spindles has advantages in the mechanical construction of the parts andin the operation of the machine. The possibility of changing the relative speeds of the spindles by changing the size of the pulley e meets the wants of thoselwho from time to time and to suit variouskinds of fabric vary the proportion of the twist given to the threads, so that the doubled thread laid upon the bobbin onthe spindle g Will-have a greater or less twist in proportion to the twist in the threads drawn from the bobbins on the spindles h h. It will be observed that the position of the two pulleys m m allows of a considerable variation in the size of the pulley ewithout in any way affecting therunning-line of, the belt is.

In the drawings I have placed the designating-letters g and h on the whirls of the re spective spindles, intending thereby to designate the spindles as entireties, as the whirl of each spindle is an integral part thereof. H i

I will now describethecarrier-pulleys a and f and the belt-tightening appliances connected therewith. The rails 64 are extended at one end of the machine beyond the frame a. I have lettered this extended part a The inner edge of the part a of the railis channeled, as shown at a This channeling extends to a point beyond the frame a and in A block t I A plate a is next placed in the two channels. This plate carries the pillar f which supports the pulley f-. A-second plate a is then placed in the two channels. This plate carries the pillar .6 which supports the pulley e, The pillar c has a projecting part 6 A screw '6 passes through and is threaded in the block. i and extends to and bears upon ablock e that is connected by the spring 6 with the projecting parte The pressure of the spring 6 upon the projection e of the pillar. 6 tends to slide,

the plate '0 in its channels and by thus'increas ingthe distance between the pulleys e and e keeps the belt is taut. If the spring becomes slack, it can be tightened up by turning the screw; in the block t. Ascrew' f 5 is'threaded in the block 6, extends toand bears upon a block f, that is connected by a spring f ywith a projection f upon the pillar f. The

screw f is to tighten the spring f which spring acts upon the plate a to tighten the belt Z in the same manner that the spring 6 acts upon the plate o to tighten the belt I prefer that the pulleys e and f shall have separate supports in order to be able to tighten the respective belts independently of each other, which could not be done if said pulleys were on the same support.
